Eur J Hum Genet 2017; 25:1106-1112.

Abstract
This paper explores the views and expectations of patients concerning recontacting in clinical practice. It is based on 41 semi-structured interviews conducted in the United Kingdom. The sample comprised patients or parents of patients: without a diagnosis; recently offered a test for a condition or carrier risk; with a rare condition; with a variant of unknown significance - some of whom had been recontacted. Participants were recruited both via the National Health Service (NHS) and through online, condition-specific support groups. Most respondents viewed recontacting as desirable, however there were different opinions and expectations about what type of new information should trigger recontacting. An awareness of the potential psychological impact of receiving new information led some to suggest that recontacting should be planned, and tailored to the nature of the new information and the specific situation of patients and families. The lack of clarity about lines of responsibility for recontacting and perceptions of resource constraints in the NHS tended to mitigate respondents' favourable positions towards recontacting and their preferences. Some respondents argued that recontacting could have a preventative value and reduce the cost of healthcare. Others challenged the idea that resources should be used to implement formalised recontacting systems - via arguments that there are 'more pressing' public health priorities, and for the need for healthcare services to offer care to new patients.

Abstract
Western history of thought abounds with claims that knowledge is valued and sought. Yet people often choose not to know. We call the conscious choice not to seek or use knowledge (or information) deliberate ignorance. Using examples from a wide range of domains, we demonstrate that deliberate ignorance has important functions. We systematize types of deliberate ignorance, describe their functions, discuss their normative desirability, and consider how they can be modeled. To date, psychologists have paid relatively little attention to the study of ignorance, let alone the deliberate kind. Yet the desire not to know is no anomaly. It is a choice to seek rather than reduce uncertainty whose reasons require nuanced cognitive and economic theories and whose consequences-for the individual and for society-require analyses of both actor and environment.

Abstract
This manuscript describes the ways in which genetic counseling has evolved since John Pearson and Sheldon Reed first promoted "a genetic education" in the 1950s as a voluntary, non-directive clinical tool for permitting individual decision making. It reviews how the emergence of Huntington's disease (HD) registries and patient support organizations, genetic testing, and the discovery of a disease-causing CAG repeat expansion changed the contours of genetic counseling for families with HD. It also reviews the guidelines, outcomes, ethical and laboratory challenges, and uptake of predictive, prenatal, and preimplantation testing, and it casts a vision for how clinicians can better make use of genetic counseling to reach a broader pool of families that may be affected by HD and to ensure that genetic counseling is associated with the best levels of care. © 2016 Wiley Periodicals, Inc.

Abstract
PURPOSE With rapid advances in genetic technologies, new genetic information becomes available much faster today than just a few years ago. This has raised questions about whether clinicians have a duty to recontact eligible patients when new genetic information becomes available and, if such duties exist, how they might be implemented in practice. METHODS We report the results of a systematic literature search on the ethical, legal, social (including psychological), and practical issues involved in recontacting former patients who received genetic services. We identified 1,428 articles, of which 61 are covered in this review. RESULTS The empirical evidence available indicates that most but not all patients value being recontacted. A minority of (older) articles conclude that recontacting should be a legal duty. Most authors consider recontacting to be ethically desirable but practically unfeasible. Various solutions to overcome these practical barriers have been proposed, involving efforts of laboratories, clinicians, and patients. CONCLUSION To advance the discussion on implementing recontacting in clinical genetics, we suggest focusing on the question of in what situations recontacting might be regarded as good standard of care. To this end, reaching a professional consensus, obtaining more extensive empirical evidence, and developing professional guidelines are important.

Abstract
HD is a complex illness, with a broad clinical picture that begins years before clear motor onset and evolves over decades to a terminal state of extreme disability. It challenges the resources of families and communities and the skills of medical and ancillary health care providers. A broader understanding of the phenotypes, progression, and genetic basis of HD may elevate the standard of care for these deserving patients.

Abstract
PURPOSE To assess attitudes towards predictive testing for autosomal dominant retinitis pigmentosa (ADRP). METHODS A prospective questionnaire study of 46 affected adults and their adult family members identified from pedigrees clearly consistent with ADRP or who had had DNA-testing confirmation of ADRP before the study commenced. RESULTS High proportions of unaffected siblings (73%) and patients (67%) agreed to prenatal testing. Patients agreed to prenatal testing. Patients agreed significantly more often than unaffected siblings that treatment should be available prior to initiating predictive testing. Psychoemotional distress was reported in 57% of the affected adults and their family members in recollecting their own predictive testing as children. CONCLUSIONS ADRP families indicate a favorable attitude towards testing presymptomatic children with counseling to lessen the psychological and social impact of results.

Abstract
PURPOSE Glaucoma is a major cause of visual impairment and blindness in developed countries. Half of those with glaucoma are unaware that they have the disease. Mutations in the myocilin (MYOC) gene are responsible for 3 to 5% of primary open angle glaucoma, thus predictive DNA testing in family members of some glaucoma pedigrees is possible. We wished to determine the attitudes of affected and unaffected family members to the use of predictive DNA testing in glaucoma. SUBJECTS AND METHODS We surveyed the attitudes of family members from one such pedigree to determine the acceptability of predictive DNA testing. We studied 72 members of a large family in which the MYOC mutation, THR377MET, segregates. Family members were examined over an 8-year period as part of research initiated to identify the gene. Once the mutation was identified, we offered participants the result of their DNA test after a genetic counseling session. Family members were subsequently given a questionnaire about the counseling and DNA result. RESULTS Most wished to know their result after counseling; 26 of 27 (96%) felt the genetic counseling session was necessary, but participants' attitudes varied as to whether they preferred this in person, by phone, or letter. Forty three patients were resurveyed 5 years after their initial counseling session. No adverse problems relating to the predictive testing were reported, though two had been asked about DNA testing by insurance companies; 5 of 24 (21%) individuals who had been informed they did not carry the mutation were unsure if they carried the mutation 5 years after counseling, while all 19 mutation carriers (who were being examined annually) correctly recalled their mutation status. CONCLUSIONS This study suggests that predictive glaucoma testing in appropriate circumstances is acceptable to patients and their families.

Abstract
The promise of genetic medicine is to provide information, based on genotype, to persons not yet sick about their risk of future illness. However, little is known of the long-term psychological effects for asymptomatic persons learning their risk of having a serious disease. Predictive genetic testing for Huntington's disease (HD) has been offered for the longest time for any disease. In the present study, the psychological consequences of predictive testing were assessed prospectively in individuals at risk for HD during seven visits over 5 years. Questionnaires of standard measures of psychological distress (the General Severity Index of the Symptom Check List-90-Revised), depression (the Beck Depression Inventory), and general well-being (the General Well-Being Scale) were administered to the participants. A significant reduction in psychological distress was observed for both result groups throughout 2 years (p < 0.001) and at 5 years (p = 0.002). Despite the overall improvement of the psychological well-being, 6.9% (14 of 202) of the participants experienced an adverse event during the first 2 years after predictive testing that was clinically significant. The frequency of all defined adverse events in the participants was 21.8%, with higher frequency in the increased risk group (p = 0.03) and most occurring within 12 months of receiving results.

Abstract
Predictive and pre-natal testing for Huntington's Disease (HD) has been available since 1987. Initially this was offered by linkage analysis, which was surpassed by the advent of the direct mutation test for HD in 1993. Direct mutation analysis provided an accurate test that not only enhanced predictive and pre-natal testing, but also permitted the diagnostic testing of symptomatic individuals. The objective of this study was to investigate the uptake, utilization, and outcome of predictive, pre-natal and diagnostic testing in Canada from 1987 to April 1, 2000. A retrospective design was used; all Canadian medical genetics centres and their affiliated laboratories offering genetic testing for HD were invited to participate. A total of 15 of 22 centres (68.2%), currently offering or ever having offered genetic testing for HD, responded, providing data on test results, demographics, and clinical history. A total of 1061 predictive tests, 15 pre-natal tests, and 626 diagnostic tests were performed. The uptake for predictive testing was approximately 18% of the estimated at-risk Canadian population, ranging from 12.5% in the Maritimes to 20.7% in British Columbia. There appears to have been a decline in the rate of testing in recent years. Of the predictive tests, 45.0% of individuals were found to have an increased risk, and a preponderance of females (60.2%) sought testing. A greater proportion of those at < or = 25% risk sought predictive testing once direct CAG mutation analysis had become available (10.9% after mutation analysis vs 4.7% before mutation analysis, p = 0.0077). Very few pre-natal tests were requested. Of the 15 pre-natal tests, 12 had an increased risk, resulting in termination of pregnancy in all but one. Diagnostic testing identified 68.5% of individuals to be positive by mutation analysis, while 31.5% of those with HD-like symptoms were not found to have the HD mutation. The positive diagnostic tests included 24.5% of individuals with no known prior family history of HD.

Abstract
Prior to the implementation of predictive-testing programs for Huntington disease (HD), significant concern was raised concerning the likelihood of catastrophic events (CEs), particularly in those persons receiving an increased-risk result. We have investigated the frequency of CEs-that is, suicide, suicide attempt, and psychiatric hospitalization-after an HD predictive-testing result, through questionnaires sent to predictive-testing centers worldwide. A total of 44 persons (0.97%) in a cohort of 4,527 test participants had a CE: 5 successful suicides, 21 suicide attempts, and 18 hospitalizations for psychiatric reasons. All persons committing suicide had signs of HD, whereas 11 (52.4%) of 21 persons attempting suicide and 8 (44.4%) of 18 who had a psychiatric hospitalization were symptomatic. A total of 11 (84.6%) of 13 asymptomatic persons who experienced a CE during the first year after HD predictive testing received an increased-risk result. Factors associated with an increased risk of a CE included (a) a psychiatric history </=5 years prior to testing and (b) unemployed status. The frequency of CEs did not differ between those persons receiving results of predictive testing through linkage analysis in whom there was only changes in direction of risk and those persons receiving definitive results after analysis for the mutation underlying HD. These findings provide insights into the frequency, associated factors, and timing of CEs in a worldwide cohort of persons receiving predictive-testing results and, as such, highlight persons for whom ongoing support may be beneficial.

Abstract
The term "duty to recontact" refers to the possible ethical and/or legal obligation of genetics service providers (GSPs) to recontact former patients about advances in research that might be relevant to them. Although currently this practice is not part of standard care, some argue that such an obligation may be established in the future. Little information is available, however, on the implications of this requirement, from the point of view of GSPs. To explore the opinions of genetics professionals on this issue, we sent a self-administered questionnaire to 1,000 randomly selected U.S. and Canadian members of the American Society of Human Genetics. We received 252 completed questionnaires. The major categories of respondents were physician geneticist (41%), Ph.D. geneticist (30%), and genetic counselor (18%); 72% of the total stated that they see patients. Respondents indicated that responsibility for staying in contact should be shared between health professionals and patients. Respondents were divided about whether recontacting patients should be the standard of care: 46% answered yes, 43% answered no, and 11% did not know. Those answering yes included 44% of physician geneticists, 53% of Ph.D. geneticists, and 31% of genetic counselors; answers were statistically independent of position or country of practice but were dependent on whether the respondent sees patients (43% answered yes) or not (54% answered yes). There also was a lack of consensus about the possible benefits and burdens of recontacting patients and about various alternative methods of informing patients about research advances. Analysis of qualitative data suggested that most respondents consider recontacting patients an ethically desirable, but not feasible, goal. Points to consider in the future development of guidelines for practice are presented.
